In this experiment, we will be swinging a block of mass
m on a
string of length
l to
study centripetal acceleration. When we use the formula
a c = v 2 r to calculate the centripetal acceleration,
r is the
radius of the circle of the swinging block, therefore is equal to
the length
l of the
string.
Group of answer choices
True or False
Q2-A block of mass 0.89kg is swinging on a string. At the lowest point, the string tension force is measured to be 14.6N. What is the centripetal acceleration in m/s2 of the block?

The system shown in the figure below consists of a mass M = 3.3-kg block resting on a frictionless horizontal ledge. This block is attached to a string that passes over a pulley, and the other end of the string is attached to a hanging m = 1.7-kg block. The pulley is a uniform disk of radius 8.0 cm and mass 0.60 kg. (a) What is the acceleration of each block? acceleration of M = 3.3 kg _____ m/s2 acceleration...

Two blocks are connected by a lightweight string passing over a pulley, as shown in the figure below. The block with mass m1 = 16.5 kg on the incline plane accelerates up the plane with negligible friction. The block's acceleration is a = 1.40 m/s2, and the tension in the segment of string attached to this block is T1. The hanging block has a mass of m2 = 23.5 kg, and the tension in the string attached to it is T2....
